Emergency services were called to the incident at the Stewart Milne Homes site in Charleston Road around 8.40am on Monday.
The Scottish Fire And Rescue Service said it was called to a report of a partial building collapse but the construction company later said there was no collapse with some material falling within the building.
The man, who was a sub-contractor at the site, is not thought to have life threatening injuries.
John Low, managing director of Stewart Milne Homes, said: “Our thoughts are with this individual and we, along with his own employer, will be monitoring his condition and providing every support to him and his family.
“We can confirm that no structure has collapsed but it would appear that some material has fallen within the building.
“We’ve got our full HSE team on-site to make sure it is safe and secure. Once that has been ascertained, we will begin an investigation to find out what exactly happened.”
